100% silk, ultra-small dog wear, soft and comfortable to wear. - Material: 100% silk - Size: S (for ultra-small dogs) Thank you for viewing. My dog seems to dislike static electricity, and I bought this on Amazon last month, but the size didn't fit. This is a set of two. I put one on my dog's back. Therefore, I've listed it as nearly new. Please understand the above. I'm offering it at the price of one item. For reference, my dog is a Papichihuahua, about 3.2kg, so please consider this for dogs around 2kg. The sizing is small, so please check the actual measurements. The material is soft and has a smooth, silky feel.
